ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.
Meeting Spotlight
International Conference on Mathematics and Computational Methods Applied to Nuclear Science and Engineering (M&C 2025)
April 27–30, 2025
Denver, CO|The Westin Denver Downtown
Standards Program
The Standards Committee is responsible for the development and maintenance of voluntary consensus standards that address the design, analysis, and operation of components, systems, and facilities related to the application of nuclear science and technology.

The 2025 ANS election results are in!
Spring marks the passing of the torch for American Nuclear Society leadership. During this election cycle, ANS members voted for the newest vice president/president-elect, treasurer, and six board of director positions (four U.S., one non-U.S., one student). New professional division leadership was also decided on in this election, which opened February 25 and closed April 15. About 21 percent of eligible members of the Society voted—a similar turnout to last year.
Educational Session|Panel|Sponsored by Plant Reliability
Monday, August 5, 2024|3:30–5:00PM EDT|Banyan 2
The increasing trend in extreme weather events disrupting the electric grid has resulted in environmental resiliency becoming a focal point for energy providers and regulatory agencies. To this effect, INPO recently release a principles document, INPO 24-003 (Resiliency – Strengthening Defenses Against External Forces) and a Tier 2 guidance document specifically associated with assessing climate vulnerabilities, INPO 24-002 (Climate Vulnerability Assessment).
This session will provide perspective on these INPO documents and discuss next steps for utilities to ensure environmental resiliency. The session will also address a specific challenge one utility is facing due to the changes in the local environment, which is directly affecting the supply of cooling water to the station. Finally, the session will discuss challenges in the management of the seasonal readiness process and potential impacts on plant reliability.
